   A storage administrator notices that the used capacity reported by Unisphere for PowerMax is significantly higher than the actual data written by applications. The administrator suspects that snapshots or other internal data are being counted. Which action should the administrator take to get a more accurate view of user-visible capacity?

   • AIncrease the snapshot retention period to reduce the impact of internal data on capacity.
   • BEnable Data Exclusion to exclude internal copies and snapshots from capacity calculations.
   • CReconfigure the storage group to use thin provisioning for all volumes.
   • DDisable Data Exclusion to include all data in capacity reports.
